check out Redline Watersports in Madison, they always have a bunch of great used boats, right now some maristars, and older x-2's... all in the mid 20's to mid 30's http://www.redlinewatersports.com/pre_owned_list.asp
we found ours on craigslist from the MLPS part, usually lots of stuff there
I would help more but im in Florida for the next three months !!!
